DISPLAY LID.

Application filed .Tune 9, 1927. Serial No. 197,730.

My invention relates to improvements in display lids. One of its objects is to provide an improved display lid adapted to be more readily constructed and assembled. Another object is to provide an improved strip of a design adapted to form an improved display lid. Another object is to provide an improved arrangement and assembly of frame members and transparent panel adapted to be more conveniently assembled, and while holding the transparent panel in place facilitating removal and replacement broken of my improved lid, partly in vertical sec-' tion.

Fig. 4. is an enlarged sectional detail taken on line l-l of Fig. 2.

Fig. 5 is an enlarged sectional detail taken on line 5--5 of Fig.

The accompanying drawings illustrate the preferred embodiment of my invention in which represents a strip of sheet metal from which the front and sides of a sheet metal frame are to be formed by bending the sheet metal stamping shown in plan in Fig. .1 along the dotted lines of Fig. 1 to form three sides of a sheet metal frame of channel shaped cross-section. A sheet metal frame member 16 is designed to be attached near its opposite ends to the respective rear ends of one web or side of the frame member 15. A panel 1? of glass or similar transparent material is designed to be slipped from the rear into the channeled frame 15, after the frame members 15 and 16 have been assert].- bled and united.

It is desirable to construct the frame members 15 from stock which has been previously surface finished, for instance electroplated or lacquered. It is also desirable to finish the surface of the members 16, as for instance by electro-plating or lacquering the same, and also by applying advertising matter or ornamental designs to the members 16,

which can be doneto advantage beforerthe members 15 and 16 are united.

In order to provide for uniting the members 15 and 16 after they have been separately formed and surface finished the members 15 have sections of their lower webs 29. cut away at 2 1- at the ends thereof, and their upper webs are perforated at 26 opposite the cut-away portions-24. Thus when the members 15 are bent to channel shaped cross section, the portions of the upper web 25 carrying the perforations 26 come opposite and above the cut-away por tions 2 1, and. thereby provide for the introduction of hollow rivets 28 through the pen forations 2G and through corresponding pen forations 29 through the member 16, and also provide for the introduction of a riveting punch or riveting tool to the under face of the rivets to clinch the rivets so as to firmly unite the rear ends of the frame member 15 to the frame member 16 near (mpdsite ends thereof without liability to mar, injure or corrode the surface finished frame members during the operation of uniting them.

At the localities where the frame member is to be bent to form the corners of the frame, the webs 22 and 25 are notched at 30 and 31 in Fig. 1, and said notches are so proportioned that when bent to substantiah ly the form shown in Figs. 2 and +1 the notch 3 lof the side sections of member 15 willftelescope with and underlap the notch edges and thereby centrally guide and prevent the front edge 36. of the panel 17 from coming into contact with the edges 35 or with the edges 10 or 411, in such manner as to interfere with introducing the panel 17 into the channel of member 15 across the front of the f ame, which would otherwise be liable to occur in the assembly of a large percentage of the frames, thereby requiring extra time in assembling or introducing the panels and liability of injury to the frame or to the panel, due to attempting to force the panel into place against resistance encountered when the front edge of the panel reaches the front section of frame member 15. In this manner I am enabled to insure introduction of the several panels into their frames without without injury or loss of time.

After the panels have been introduced into position in the frames, the rear ends 38 material resistance, and

of the middle sections 37 and those uncutaway portions of the endsof the lower webs are bent inwardly in rear of the rear corners of the panel 17 as shown in Figs. 2 and -5 tothereby prevent the panel being retracted from the frame or becoming accidentally displaced or detached. In the event that the panel should become broken, the

bent in sections 37 may be bent outwardly sulficiently to allow the broken'panel to be removed and anew panel inserted, after which the sections 38 are bent inwardly "again'to hold the panel; in place. The inlid move in unison.

wardly turned ends 42 and 43 of the frame member-'16 enable the edges of the lid of an original package to be engaged in the channels 4i so that the original lid and display brace the front and opposite sides of said' panel with the ends'of the upper and lower webs of the side sections of said frame interposed between the faces of the panel and the ends of the upper and lower webs of the front section of said frame at the front corners of said panel, and a rear sheet metal frame member extend ng across the rear of said panel and above said panel and at tached to the rear ends of the upper web of said channel shaped frame member, said rear frame member being provided with members adapted to operatively connect said display lid to the lid of an original package.

2. In a display lid in combination with a transparent panel, a sheet metal frame member of channel shaped cross-section to embrace the front and opposite sides of said panel and with the rear ends of the upper web of said frame member erforated and the rear ends of'the lower we of said frame member cut away opposite the perforated portion of the rear ends of the upper web, and a rear frame member of angular crosssection having one web thereof perforated near opposite ends thereof to register with the perforations in the rear ends of said channeled frame member and adapted to be attached to the rear ends of the upper web of said channeled frame member bv rivets, said rear frame member being provided with members adapted to operatively connect said display lid to the lid of an original package to move in unison therewith.

3. In a display lid in combination with a transparent panel, a sheet metal frame member of channel shaped crosssection to embrace the front and opposite sides of said panel and with the rear ends of the upper web of said frame member perforated and the rear ends of the lower web of said frame member cut away opposite the perforated portion of the rear ends of the upper web and a rear frame member extending across the rear of said panel and above said panel and attached to the rear ends of the upper web of said channel shaped frame member, said rear frame member being provided with members adapted to operatively connect said display lid to the lid of an original package, and the rear ends of said channel shaped frame member being provided with bent over portions to engage the rear edge of said panel to, retain said panel in place relative to the frame.

In testimony whereof I have attixed my signature.
